Mike Prewitt (Raptor Technique) did an evaluation of one and wasn't very happy with it.

It's made by Sanye who also make Magnum , SC and ASP engines . I had a look at one , it had some swarf trapped between the liner and crankcase , which was visible at the exhaust port , so would have needed to have been disassembled and cleaned before running . The carb also looked very small for a 52 size heli engine .

The only people who truly know where the edge lies, are those who have gone over.

I run one

I added a o ring for a bit of resistance. Havent fried it even with a auxially pinion drive for the generator and I've had a actual head temp at 340F based on a direct read themocouple.

Have a confirmed tached head speed over 2000 till it would not read on the MA tachometer. Had to back it down on the curve and thats on cheap 10% didn't trust the carbons or plastic blade grips.

Will hold a very low tickover idle all day long, even starts hot or cold with same tick over, never ever had a bearing problem. Has unlimited pump on the collective. You can hear it bear down a bit but other wise always sounds like it's barely working. It's heavey though at almost a full Lb. Its a massive ugley thing but Seems to get along in my Titan. Does have a bit of a fat dwell spot at mid range - but I run it fat anyway. Mileage is getting better after about 5 gallons.

AAHHHH! Im my expirience with the evo plank motors they are terible. Most of them do not run good at all. I am usually very good at engines but I just cant make those things run good!

I have a few evo plane engines and some work great but some wont run at all! I had a .61 in a sundowner and it ran great but was pulling about 87mph when i put an o.s in it it was well over 100mph so there not great for power.
